I have a sandwich similar to this at a local coffee shop. I used a seed rye, spread one side with a roasted tomato, topped that with havarti, on goes the fried egg( I use one whole egg and I yolk and fry the egg until done but still soft in the center of the yolk, salt pepper, top the egg with sauteed spinach and little more cheese and toast in a pan sprayed with olive oil cooking spray.
